Hi Salamander and welcome to the forum
With debts of only £15,000, you are borderline for an IVA to be frank, and presumably the limited company is able to fund the guaranteed liabilities?
Why not try and write to your personal creditors and explain the situation regarding the company, giving them assurances that things are improving and asking perhaps for reduced payments for say 6 months. This way you can test for yourself whether your debt problems are manageable or whether you need to revert to professional assistance.
